Walker Products 250-24447 oxygen sensor for the 2006-2007 Chevrolet Optra 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas. This four-wire, narrow-band, direct-fit sensor is made for a specific application and fitment position and gives the ECU diagnostic feedback.
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Electrodes made of a gas-permeable platinum layer
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
Quick facts
- Part: Walker Products 250-24447 oxygen sensor
- Fits: 2006-2007 Chevrolet Optra 4-cylinder 2.0L and other vehicles
- Position: Upstream, downstream
- Condition: New
A failing sensor can make the engine run poorly, raise fuel consumption, or turn on the malfunction indicator light. Before you replace the sensor, rule out physical damage to its wiring harness and connector, since a damaged harness or connector can produce similar trouble.
Fits
This oxygen sensor fits the 2006-2007 Chevrolet Optra 4-cylinder 2.0L and the 2002-2004 Kia Spectra 4-cylinder 1.8L, and each of those cars takes one.

Frequently Asked Questions
Is this oxygen sensor right for the 2002-2004 Kia Spectra 4-cylinder 1.8L?
Yes. Walker Products 250-24447 is listed for the 2002-2004 Kia Spectra 4-cylinder 1.8L, and that car takes one sensor.
Does this oxygen sensor fit the 2006-2007 Chevrolet Optra 4-cylinder 2.0L?
Yes. Walker Products 250-24447 fits the 2006-2007 Chevrolet Optra 4-cylinder 2.0L, and the car takes one.
Does this Walker Products oxygen sensor have platinum electrodes?
Yes. The electrodes are made of a gas-permeable platinum layer, and a coating protects the electrode surfaces from combustion residue and particulates in the exhaust.
Can a failing oxygen sensor store a fault code in the ECU?
Yes. Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems. A shop can read them.
Is the 250-24447 a narrow-band oxygen sensor, and how many wires does it have?
Yes. The Walker Products 250-24447 is a narrow-band, direct-fit oxygen sensor with four wires.
